Specification of Letters latent. Patented Dec 114:, 1909-.

Application filed Augiist lG, 1907. $eria1No. 388,789.

Be it known that I, MAXIMILIAN F. JU- n Ic'K, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, in thecounty-and State of New York, have invented a new and Im-' proved lllectric-Lighting Attachment for Burglar-Alarm Systems, of which the following is a full, clear, and exact description. i

This invention relates to certain improvements in burglar alarm systems, and more p 'ticularly to means whereby all or any portion of the electric lights of a building will be placed in circuit when anyone attempts to enter the building at night, or

for any other reason the alarm bell is started in operation.

My .invention further comprises means whereby after the electric light is turned on it willbe impossible for'the burglar to com nect the electric lighting circuit to the billthus stop the alarm bell.

Reference is to be had to the accompanying drawing forming a part of this specification, and which illustrates diagrammatically my improved apparatus In the drawing I have not illustrated all of the connections to the doors, Windows ainl other points at which a burglar might 0 use the circuit upon endeavoring'to obtain admission to the building, but have merely illustrated two terminals 1 and 2, which may be located aei acent any'window or door or ad jacent the alarm bell, and so constructed that these terminals would. be brought together should an intruder attempt to enter. One.

wire 3, as shown, is connected tothe: carbon side. The terminal 2 is. connected to the zinc side by means of a wire 4,.and'in this wire 4 is located the automatic drop, whereby the current is turned on to the electric bell when the two terminals 1 and 2- am brought together. The wire 4;from the terminal 2 passes first through the coils of an electro-' magnet 5, and thence to a pivoted lever .6-

normally held in place by the armature 7 of 'lar alarm circuit and ruin the batteries and the electro-magnet and having the pivoted end of the lever in connection with the frame 8 of the electro-magnet, which latter is electrically-connected to the zinc side of the battery.

- An electric bell 9 ,is provided, one terminal of which is in direct communication with the carbon side of the battery, either by means of a 'wire extending direct to the battery or, as herein shown, by a branch wire 10 leading to the wire 3 above referred to. The opposite terminal of the electric bell communicates by means of a wire 11 with a terminal 12 adjacent the pivoted lever 6 and adapted to act asa stop for said lever when the same isreleased by the withdrawal ofv the armature 7 at the time the electro-magnet is energized.

in any other manner, the circuit is closed and the current passes through the wire 3, the terminals 1 and 2, the wire-4, the coils 5,

.It will' be noted thatfas the terminals 1 the lever 6, and the frame of the magnet back to the battery. As soon as the coils are energized, the armature 7 is drawn to a position where it releases the lever 6, and as the latter drops down into contact with the terminal 12, a current may then pass from the carbon side of the battery directly to the electric bell and through the wire 11,.through the terminal 12 to the lever 63, and thence to the-frame of the electro-magnet and back to the battery;- ,The circuit through the electro-m agnet 5 is now broken, and even though the terminals 1 and 2 are immediatelyseparated, this will not serve to stop the ringing oftlie egactric bell, as the terminal 12 is now dea and not connected to the battery in any way. Furthermore, it will be impossible toruin the battery by sending a strong electric-lighting current in the terminals 1 and 2.

, Arranged in parallel with the electric bell 9 are two electro-magnets, one of which serves as an automatic drop to break the fcircriit after it has performed the desired function, While the .other electro-magnet serves to throw the electric lighting swltch. The elect-ro-magnet 13 is at all times in communication with thecarbon side of the I batterythroiigh a wire 14, while the opposite end-of the coil of this electro-magnet contacts at a point with a'pivoted lever 16 carried by the frame of the electro-mag,

net. A wire 17 connects the frame of'the -magnet with coils of the second electromagnet 18, and the opposite 'ends of these coils communicate by a wire 19 with the terminal 12 of the alarm system. Adjacent the electro-magnet 18 is a lar e weighted switch 19 which is normally held open by the armature 20 of the electro-magnet l8 and which when closed serves to permit the passage of a current of high voltage fromany suitable source 21 through all of the electric lights 22 of the building, or any desired por= tion thereof. The weight 23 of the swltch is sufficiently, heavy to lnsure the closing of the switch when the armature 20 is' withdrawn, and as the electro-magnet 18 is in.

parallel'with the electric bell 9, llLWill be seen I that the electric lights'are all lighted simulutheeclo sing ofthe'c'ircult at the terminal12' taneously with the ringing of the alarm bell. As soonas the current is permitted to pass through the electro-magnets 13 and 18 by and 'the lever 6,-the current is almost-inthe illumination of the building, he might endeavor by the aid of a loupleof short pieces of heavy wire. or other conduetor, to

place the wires 17 and 19 leading to the electro-magnet 18, in "communication with 40. ringing; but, as itwill be noted, this is im the opposite terminals. of the electric lighting system, and thus endeavor to ruin the battery ofthe alar'm'bell and stop it from possible, as the wire 17 is no longer in com- Imunication with the. battery, due to the breaking of the circuit at the terminal 15 and the pivoted lever 16.- Should he discover the electric lighting switch and its operating mechanism before he had sounded the alarm and before said alarm wassounded endeavor to ruin thebatteries' by astrong current from the electric lighting circuit, he

-would be foiled first by'reason of the fact that thewire 19 does not normallycommunicate with the battery as it is broken a't the terminal 12, while even if it were in com munication with the .battery the current through .the wire 17 would. be broken as soon as the electro-magnet 13' was energized and before any damage could be done to the battery;

A suitable switch 24 preferably provided in the wire 17, so that during the daytime this portion of the system 1s thrown out of circuit, and it will be possible for the electric bell ,to be controlled by any suitable clockwork, not shown and thus serve to incircuit. I
